It is not to be wondered at that we do not find any Crocodilian in 
our lists, as those animals prefer the damp and hot climate of the 
lowlands, with the flat and level banks of slowly moving rivers and 
streams ; but we should have expected to find several species of Tor- 
toises extending upwards to the subtropical zone. Yet neither Dr. 
Hooker nor Mr. Blyth mentions their occurrence*, and the single 
specimen of Hmyda punctata in the collection of MM. von Schlagint- 
weit is, at present, the only known representative of this order in 
the Himalayas. The absence of Crocodiles and the scarcity of Tor- 
toises appear to distinguish the outer Himalayas from the plains. 
The ratio of the numerical distribution through the various alti- 
tudes is different in the different orders of Reptiles. Whilst the 
number of the species of Lizards (strangely enough) does not decrease 
between 1000 and 15,000 feet, the number of Snakes and Frogs de- 
creases very steadily with the increasing elevation, From the. above 
list we find— 
16 Snakes and 5 Batrachians at 1000 feet.

* Several freshwater Tortoises, sent by Mr. Hodgson from Nepal, belong to the 
lowland fauna, being the most common species at the mouth of the Ganges.
